Run current change via dipswitches on configuration board 3. Hold current change via dipswitches on configuration board 4. Damping modes for smoother motion 5. Selection of sensing the step pulses on the rising edge or falling edge 6. Selection of sensing the direction change on the rising or falling edge 7. When disabling the unit, selection of either having power or no power to the unit 8. Only one configuration module is necessary; a single module can be used to configure multiple IMD23 units
